dude has my nose. Jaw is too small. You need to study ear and eye more. Mouth isn't conforming to planes of face enough, right side is moving off of face into the air. The uhhh, dimple thingy between lips and nose isn't on the center line. Could maybe work in a bit of the neck-to-jaw connection, even at that angle, with tones.
Thats all I notice now. All that said its a good attempt at no ref head.
